In ‘Parts Unknown,’ Bourdain is not a man on a mission

As he premieres the fourth season of Parts Unknown, Anthony Bourdain clarifies that he’s not an expert, just a 'lucky son of a b****'.

Anthony Bourdain’s TV travelogue Parts Unknown goes to Iran to discover how people live behind the geopolitical smoke screen and to small-town Massachusetts to chronicle the heroin scourge. But even if the fourth season of his Emmy Award-winning CNN show fosters cultural diplomacy or raises drug awareness, this outspoken New York chef insists he is on no kind of socially minded mission. And he’s not an advocate, activist, journalist or expert on anything.
